Two-session endoscopic purse-string suture to close a huge esophagojejunal anastomosis thoracic cavity fistula
22 October 2018 (eFirst)
Esophageal anastomosis leaks or fistulas are life-threatening conditions after surgery and have high morbidity and mortality. Traditionally, neither surgical repair nor conservative therapy could improve the prognosis effectively. In recent years, endoscopic methods, such as using esophageal stents, OverStitch (Apollo Endosurgery, Austin, Texas, USA), and the Over-the-Scope Clip system (Ovesco Endoscopy AG, Tübingen, Germany), have been an effective alternative to surgery   . However, it remains a challenge to endoscopically close huge fistulas, especially those larger than 30 mm. We report the method of endoscopic purse-string suture with clips and endoloops for the closure of a huge esophagojejunal anastomosis fistula .
A 74-year-old man diagnosed with cardiac carcinoma underwent laparoscopic distal esophagectomy and total gastrectomy. However, he presented with progressive shortness of breath 5 days after surgery. Upper gastrointestinal imaging showed anastomosis leakage. Gastroscopy revealed a huge esophagojejunal anastomosis thoracic cavity fistula of approximately 35 mm in size located at the right wall of the anastomosis ([Fig. 1]). A nasojujunal feeding tube was implanted deeply beyond the fistula. Gastroscopy 2 weeks later revealed that the fistula had not significantly decreased. Given the poor condition of the patient, surgery was abandoned and closure of the fistula by endoscopic purse-string suture was attempted ([Video 1]).

A 3-cm loop (MAJ-254; Olympus, Tokyo, Japan) was selected according to the fistula size. After adjustment of the location and angle of the endoloop, it was anchored onto the edge of the fistula with nine clips at different sides, aided by simultaneously tucking the edge with slight suction. The defect was then successfully closed by tightening the loop. Gastroscopy 1 month later revealed that the fistula had decreased to 10 mm in size; endoscopic purse-string suture was repeated ([Fig. 2 a]). Gastroscopy 1 month after this repeat procedure showed that the defect had completely closed ([Fig. 2 b]).
This case suggests that endoscopic purse-string suture may be an effective and feasible method for closure of huge anastomosis fistulas, but multiple sessions might be needed.
